So.. secret codes are a myth, and here are some examples of secret codes?
...sigh:
Secret codes as in "watermark-level omission of characters" are a myth. Lingo and jargon do however exist, and convey meaning in a particularly subtle way. They are shared and taught by culture, not by a secret handbook passed down from generation to generation. See also dogwhistling.
The goal is to protect the issuer, not to selflessly inform the recipient.
> You will be lucky to have this person work for you.
This isn't a veiled statement. It's outright dunking on the applicant.
I think there's some deeper issue with the language/culture here.
> you would be lucky to get this employee to work for you!
